Hydroelectric generator set ndi chipangizo chosinthira mphamvu chomwe chimasintha mphamvu yamadzi kukhala mphamvu yamagetsi. Nthawi zambiri amapangidwa ndi makina opangira madzi, jenereta, bwanamkubwa, makina osangalatsa, makina ozizirira komanso zida zowongolera magetsi.
(1) Hydraulic turbine: pali mitundu iwiri ya ma hydraulic turbines omwe amagwiritsidwa ntchito kwambiri: mtundu wamagetsi ndi mtundu wamachitidwe.
(2) Jenereta: majenereta ambiri ndi majenereta osakanikirana, omwe ali ndi liwiro lotsika, nthawi zambiri pansi pa 750r / min, ndipo ena amakhala ndi maulendo angapo / mphindi; Chifukwa cha liwiro lotsika, pali mitengo yambiri ya maginito; Kukula kwakukulu ndi kulemera kwake; Pali mitundu iwiri yoyika mayunitsi a hydraulic jenereta: ofukula ndi yopingasa.
(3) Kuwongolera liwiro ndi zida zowongolera (kuphatikiza kazembe wothamanga ndi kazembe wamafuta): ntchito ya kazembe wothamanga ndikuwongolera kuthamanga kwa hydraulic turbine, kuonetsetsa kuti kuchuluka kwa mphamvu zamagetsi kumakwaniritsa zofunikira zamagetsi, ndikukwaniritsa ntchito yagawo (kuyambira, kutseka, kusintha liwiro, kuchuluka kwa katundu ndi kuchepa kwa katundu) Choncho, ntchito ya bwanamkubwa idzakwaniritsa zofunikira za ntchito yofulumira, kuyankha tcheru, kukhazikika kwachangu, ntchito yabwino ndi kukonza, komanso kumafunikanso ntchito yodalirika yamanja ndi zipangizo zozimitsa mwadzidzidzi.
(4) Dongosolo losangalatsa: jenereta ya hydraulic nthawi zambiri imakhala jenereta yamagetsi yolumikizirana. Kudzera muulamuliro wa DC excitation system, kuwongolera mphamvu yamagetsi yamagetsi, kuwongolera mphamvu yogwira ntchito ndi mphamvu zogwira ntchito ndi zowongolera zina zitha kutheka kupititsa patsogolo mphamvu yamagetsi yotulutsa.
(5) Kuzirala dongosolo: mpweya kuzirala makamaka ntchito yaing'ono hayidiroliki jenereta kuziziritsa stator, rotor ndi chitsulo pakati pa jenereta ndi mpweya mpweya. Komabe, ndi kuwonjezeka kwa mphamvu imodzi ya unit, kuchuluka kwa matenthedwe a stator ndi rotor kumawonjezeka nthawi zonse. Kuti kuonjezera linanena bungwe mphamvu pa unit buku la jenereta pa liwiro linalake, lalikulu mphamvu hayidiroliki jenereta utenga mwachindunji madzi kuzirala akafuna stator ndi wozungulira windings; Kapena mafunde a stator ndi utakhazikika ndi madzi, pamene rotor ndi utakhazikika ndi mphepo yamphamvu.
(6) Zida zowongolera masiteshoni: zida zoyendetsera magetsi zimakhazikitsidwa makamaka ndi ma microcomputer, omwe amazindikira ntchito za kulumikizana kwa gridi, kuwongolera voteji, kusinthasintha pafupipafupi, kuwongolera mphamvu, chitetezo ndi kulumikizana kwa ma hydraulic generator.
(7) Braking chipangizo: majenereta onse hayidiroliki ndi mphamvu oveteredwa kuposa mtengo wina ali okonzeka ndi braking chipangizo, amene ntchito mosalekeza ananyema rotor pamene liwiro yafupika 30% ~ 40% ya liwiro oveteredwa pa shutdown jenereta, kuti kupewa kukankhira kubala kuwotcha chifukwa mafuta filimu kuwonongeka pa liwiro lotsika. Ntchito ina ya chipangizo cha braking ndikulumikiza mbali zozungulira za jenereta ndi mafuta othamanga kwambiri musanayike, kukonza ndi kuyambitsa. Chipangizo cha braking chimagwiritsa ntchito mpweya woponderezedwa pobowoleza
